I encountered a small bug in Bridge 2023. In the Metadata Panel I usualy hide the Placard. I also like to expand the File Properties. Before Bridge used to remember my settings. Now every time I open Bridge the Placard is back and the File Properties is collapsed.
The issue as mentioned by topic starter is not resolved in the update. I still have to expand all the info panels. (File properties, IPTC core, Camera data) manualy every time.
I have noticed in the Preferences->Metadata there is a function at the bottom 'show Metadata placard' Which you can check/uncheck. I always have the placard visible so i do not know this is a new function or not.
There is a mention in the fixed issues list: "Metadata Placard does not show up in the Metadata panel."
